Brief Summary:
This is a double-blind, placebo-controlled, multicenter, efficacy and safety study of firibastat (QGC001) administered po bid over 12 weeks in male and female subjects ≥18 years of age at Screening, with uncontrolled primary HTN. Subjects will be randomized 1:1 to investigational product (IP) and will receive either firibastat (QGC001) or matching placebo on top of their current chronic antihypertensive treatments.

Condition or disease Intervention/treatment Phase
Hypertension Drug: Firibastat Drug: Placebo Phase 3

Detailed Description:
The primary objective of this study is to assess the effects of administration of firibastat (QGC001) 500 mg oral (po) twice daily (bis in die [bid]) on blood pressure (BP) over 12 weeks in subjects with uncontrolled primary HTN.
